Patent DE-2011237-B2 (DE)
Title: Tachogenerator control for electrically cocked gun - switches drive off when breech block reaches preset speed
IPC: F41A7/06
Filed: 1970-03-10
Abstract: The breech block of an automatic gun is pulled back into the cocked position by a chain, driven by an electric motor via a magnetic clutch. The speed of the drive is measured by a tachogenerator. To cock the gun, the motor is switched on and, after 0.3s delay, the clutch engaged. When the drive reaches a preset speed, or when the cocking position is reached, whichever is sooner, a controller disengages the clutch and switches off the motor. The motor has sufficient torque to pull the breech block fully back, in spite of high friction or a jammed cartridge. The tachogenerator ensures that it will not hit the end stop at excessive speed if there is no resistance. (US).

Title: Turnover plough actuator - has leakage oil container with spring-loaded piston or diaphragm, connected to working cylinder and duct from valve
IPC: A01B3/421
Filed: 1970-04-21
Abstract: Turning unit for a turnover plough with a hydraulic drive whose piston reciprocates during the full turnover of the plough and whose working cylinder, filled with hydraulic oil in the working position and shut off by a valve, presses the plough against a stop. A leakage oil container with a spring-loaded piston or diaphragm is connected to the working cylinder and to the duct leading from the valve to this cylinder, and contains more oil than there can be lost between two turnover operations of the plough. Either a press. is maintained in the leakage container greater than the liq. press. exerted by the plough in the working cylinder, or when a spring is used in the container with a press. maintained in the container less than that exerted by the plough, an additional shut-off element is fitted, and is controlled by the piston of the leakage oil container. The effect of oil losses in the system is minimised.

Title: Circuit for manually setting pilot signal control circuit - uses rotary capacitor as timing element in rectangular wave generator whose output is integrated
IPC: H04B3/10
Filed: 1971-02-17
Abstract: The manual setting circuit, for adjusting the reference level of a pilot signal control circuit in a carrier wave system, has no sliding contacts but instead uses a rotary capacitor (DK) acting as timing component in a rectangular wave oscillator (RG). The rotary capacitor alters the oscillator's duty factor. The oscillator's output is integrated (RC). A change-over switch (U) connects either the oscillator's integrated output to the input of a level discrimination (PD) or the output of the pilot signal rectifier (PG) to the same input.
